ball valves in stainless steel GAZOMET manufactures also ball valves in stainless steelversion for application in systems filled with aggressive media.Ball valves of this type are individually designed and adjusted tosubmitted performance conditions, especially to the type of medium and the application temperature and pressure. Ballvalves designed in this way, guarantee quality performance formany years of operation.

VIII. Special version

Ball valve with metal-metal sealingBall valves with metal-metal sealing (KDKa and KDSa) have beenthe first Polish design implemented in production. This type ofsealing guarantees long durability and stability in harshconditions. Ball valves of this type, having special sealingpackages, are fireproof and maintain leakproof properties intemperatures of up to 650°C over a 30-minute time.

IX. Engineering solutions

Cross-couplingGAZOMET has introduced a new solution to ball valve design,linking the ball with the stem with a cross coupling. This allowsfor the ideal adjustment of the ball position to the seals in thefull rotation range (90°). Such a configuration eliminatesunfavourable stress in the valve, which makes the rigid stemmounting and the cross coupling more stable. Reduced torqueprovides uniform distribution of ball pressure on the seals aroundthe entire circumference, which improves leakproof performanceof the whole sealing system.

Sealing compensation

Ball valves manufactured by GAZOMET are provided with elasticcompensation of the main sealing. This compensation is ensured by the special corrosion-resistant spring packages.This solution allows for a uniform and controlled pressure of thesealing package to be applied to the ball surface, eliminatingmounting stresses and improving the performance of the ballvalve under a wide range of temperatures and pressures. All thisprovides a reliable ball valve performance in the long run.GAZOMET always uses the double, independent sealingcompensation, while maintaining the “Double Block and Bleed(DBD) function, which guarantees some leakproof properties ofthe valve in its inlet and outlet sections while completely closed(Fig.2) or opened (Fig. 3). This feature enables leakproof teststo be performed via the plug or the drain valve.

Engineering solutions

Fig. 2

Fig. 3


9www.gazomet.pl

GAZOMET proposes two solutions of sealing compensation:

1. Single Piston Effect (SPE) - single sealingAt the inlet this solution provides a tight closure around the sealthat is pressed upon by the force coming from the springpackage and the medium inlet pressure (Fig.4). In the SPEconfiguration, the excessive pressure, which may occur in thedead zone of the ball valve during the closing or openingprocedure, is automatically released into the pipeline at theoutlet of the valve (Fig.5).

2. Double Piston Effect (DPE) – double sealingThe valve tighness is ensured by a complex sealing package atthe inlet, where the seal is pushed by the forces produced bythe spring package and the inlet medium pressure (Fig. 6), andat the outlet, where the seal is affected by the forces producedby the spring package and the medium pressure in the deadzone of the valve (fig. 7). This solution ensures that the valve isleakproof even if the first package fails. The DPE system doesnot have the feature of automatic pressure release, which mayoccur in the dead zone of ball valve, when it is being opened orclosed.


Fig. 4

Fig. 5

Fig. 6

Fig. 7

10

Safety sealing systemBall valves, especially those with larger diameters, have beendesigned to include a safety sealing system and lubrication. Incase of failure of any valve seal, the system injects sealing pasteonto the defective area to restore sealing properties.

Stem sealingDepending on ball valve type, GAZOMET offers two stem-sealing solutions:

1. Single-stage - consisting of two “o-ring” seals 2. Multi-stage – combining o-ring and MUPU seals with graphite

fireproof package. This solution allows for the replacement of the upper seals with undisturbed pipeline operation (note: proceed with replacement acc. to the „Operation Instructions").

All the stems are anti-blow protected and mounted either on theinside or the outside of the housing; a protective flange is usedin the latter.

Antistatic protectionIn ball valves, the ball is electrically insulated by plastic sealsfrom the valve body. Opening or closing of the ball valve, as wellas friction of the flowing medium, induces electrical charges onthe ball surface. Metallic connection of the ball, the stem andthe body will carry the electrical charge. Antistatic protection is very important when flammable andexplosive media are used.

X. New technologies

Numerically controlled machine toolsGAZOMET is a manufacturing organisation, where the stock ofmachine tools is subject to continuous upgrading. A consequentinvestment process allows for systematic replacement ofconventional machine tools with new, more precise and efficientmachine tools that are numerically controlled.The Boehringer turning centre is one of the latest CNCmachines, used by GAZOMET. This machine provides highrigidity of machining, high efficiency and manufacturingprecision. It allows the machining of parts that are up to 550mm in diameter, with length of up to 1000 mm and max weightof 800 kg. This machine is equipped with an additional “C” axle,which, with the use of driven tools, enables drilling operationsand milling around the perimeter.

Extensive manufacturing experience of GAZOMET combinedwith application experience of the end-user leads to conclusionthat the high quality of ball valves, i.e., their tightness, dependson the performance and matching of the two main elements: theball and the sealing. In the dynamic sealing provided by thesealing component, the quality of the ball manufacturing,especially its perfectly smooth surface, miniscule deviations inshape and the radial run-out are the key important features.

Supfina superfinisherGAZOMET possesses a special ball superfinisher. TheSUPFINA superfinisher is the only new generation machine toolin Europe, which provides high quality surface finish (Ra parameter < 0,16 µm) and roundness deviations < 0.02 mm.

XI. Drives

All ball valves, depending on the torque required to open a valve,are equipped with a wrench or a worm gear. Optionally, ballvalves may have their own drive system: electric, pneumatic orelectro-hydraulic.

Drives

Manual drive (a worm gear) Electric drive (AUMA)

Pneumatic drive (NIWATEC) Electro-hydraulic actuator (Fahlke)


13www.gazomet.pl

Ball valves intended for underground application come with stemextensions. GAZOMET offers two types of extensions:

Rigid extension (KLo, KL)It is of constant height measured from the ball valve axis to theupper part of the stem or to the drive rotation axis.

Notes: 1. The “H” dimension can be changed on the Customer’s request.2. KLo extensions, in their standard configuration, feature a vent

plug.

Telescopic extension (KT)An extension of specified height with height regulation mode(400 mm). No drive can be mounted on a telescopic extension.
